PROCESS OF AND APPARATUS FOR MAKING COAL-GAS.

SPECIFICATION forming part of Letters Patent No. 266,326, dated October 24, 1882. Application filed November '7, 1881. (N model.)

To all whom it may concern Be it known that I, ANTON STAMM, a citizen of the United States, residing at Leadville, in

the county of Lake a invented certain new in Process of and Apparatus I declare that the following is a full, exact description of the invention,

Gas; and clear, and

nd State of Colorado, have and useful Improvements for Making Coalwhich will enable others skilled in the art to which it appertains tomake and use the same.

Hitherto the tar vapors that arise from fresh ly-charged coal-gas retorts have been driven into other more in ghly heated retorts by means of steam-jets and by their own pressure, but

tains a large proportion 0 gas produced with the admixture of steam conf non-luminous ingredients, which reduce the candle-power of the gas; an

d if the tar-vapors are made to pass through other retorts by their own pressure or tension, then they are not removed fast enough from the generating-retorts to relieve the latter promptly of the pressure.

The object of my invention is to inject the tarry vapors successively 2 freshly-charged and decomposing retort fil from a number of gas-retorts into a regenerating led with incandescent coke by means of a jet of highly-compressed coal-gas used as a I attain 3c the accompanyin n injecting agent.

this object by the apparatus shown in g drawings, in which- Figure 1 is a vertical section, showing also some parts in perspective; spective view of the ot' the apparatus.

and Fig. 2 is a pertop and part of the front Similar letters refer to similar parts throughout the two views.

To carry my invention in the dip-pipes 0 0 c c with t to effect, I connect he lateral pipes m m m m, and these latter with the pipe (1. The

rear end of the said retort r the pipe d is met and pene- (1 lies horizontally upon the gas-oven, the water-main to the rear end Thence it turns downward, ex-

bottom of the re- Here it bends inward and enters the by the opening E.

e injector j. The

horizontal pipe 8 (behind the retort r) is filled with highly-compressed coal-gas.

so taken either from the gashe gas is holder or from the pipe C, and is compressed in a (water-j acketed) cylinder with a piston worked by a steam-engine. On opening the stop-cock t the compressed coal-gas issues from the nozzle of the injector and forms a very forcible jetin the middle of the lower end of the pipe d. 0 0 0 0, Fig. 2, are valves for the opening and closing of the dip-pipes c c c c, and t t t t are valves for the lateral pipes m m m m.

The mode of operation is as follows: The retort r, being the upper one of a bench of retortsp, q, &C.lS filled with coke once every day, and is constantly kept at a bright-red heat. The gas evolved in rpasses through the pipes at, I), and 0 directly into the water-main. The other retorts are filled with coal, say, every six hours each. If there are six retorts besides 1* in the bench, then one of the retorts is filled every hour. During the first hour'ot' distilling the coals in any one of the six retorts the valves of the respective dip-pipe c and lateral pipe m (which are in communication with the last-charged retort) must be so arranged as to allow the tarry vapors from the said retort to pass freely into the pipe (1. After one hours distillation the valves are reversed, so that the now perfect gas from the said retort can-pass directly from the respective dip-pipe 0 into the hydraulic main. Then another one of the six retorts is charged with fresh coal, and the valves of its dip-pipecand lateral connecting-pipe m are so placed as to allow the tar-vapors from the said retort to pass freely into the. pipe d, 850. Thus the six retorts are charged one after'another at intervals of one hour, and the vapors from each during the first hours distillation are made to pass into the connecting-pipe d by closing the valve 0 in the respective dip-pipecaud by opening the valve t in the respective. lateral con- 0 necting-pipe m. In the pipe (I the tar-vapors are drawn downward by the induced current caused by the action of the gas-jet from the injector j, and after arriving at the lower end of the pipe (1 they are forcibly injected into 5 the rear partof the retortr and driven through the whole length of the retort by the same injecting jet of compressed gas. 1n the retort. r the vapors are converted into a fixed gas, which passes directly to the hydraulic main.

Now, I do not claim, broadly, the conversion of thetarry vapors given ofi'from fresh charges in coal-gas retorts into fixed gas by blowing them into other more highly heated retorts than those from which they have arisen, nor the reciprocal action of twin retorts in their distilling and regenerating operations, nor the application or steam as the agent and material for injecting the tarry vapors.

hat I claim as my invention, and desire to secure by Letters Patent, is-

l. The improvement in the process of manufacturing gas which consists in converting the tarry "apors given off from a fresh charge of bituminous coal during the early part of the distillation into a fixed gas by injecting such vapors by a jet of coal-gas under pressure into and through a mass of incandescent coke in a separate retort, as hereinbcfore described.

2. In a plantfor manufacturing coal-gas,the combination, with the distilling-retorts p, &c., the stand-pipes a a, &c., the dip-pipes c c c c, and the hydraulic main h, of the connectingpipcs m m m m and (I, provided with valves, the injector j, and theretort 1', all substantially as described, and for the purpose specifled.
